The steel C60S is used as cold rolled strip for springs and special applications in thicknesses of up to 6 mm and as tempered cold strip in thicknesses from 0.30 to 3.00 mm. The cold-rolled steel strip for springs possess a very high precision of measurements and very good state of the surface.
We hold expertise in providing a qualitative range of Blue Tempered Steel Strips to our clients at affordable prices. Owing to features like high efficiency, optimum performance and durable finish standards they are highly demanded in the market. Our ranges of these are used in various industries like automobile, cable and electronic industries.
In annealed and lightly rolled materials, they exhibit a large degree of elongation, and can withstand complex processing. Springs are used in plenty of applications in the present-day world. Even so, only a few people have a nodding acquaintance with the brass tracks of spring manufacturing and the different qualities needed for various functions. While coiling steel into a spiral of desired length and diameter is the primary and center-most stage of spring fabrication, other treatments during and after the procedure determine the quality of the product that reaches the consumer.
high carbon steel Annealed tempered spring steel strip is harder, less bendable, and has a higher degree of spring back. Finished products made from this material have better edge retention, which correlates to the material's other properties. Annealed spring steel strip is used widely in the manufacture of springs, prominently in automotive and industrial suspension applications. It is a high carbon steel with a very high yield strength. This material allows objects made of spring steel to return to their original shape despite significant deflection or twisting.
